6 6 6. Attending conferences/writing papers/lab From: Austin Herrema [] Sent: Wednesday, January 14, 2015 2:19 PM To: McCalley, James D [E CPE] Subject: Re: WESEP 594 Hi Dr. McCalley, I'm actually at the NREL Wind Energy Systems Engineering Workshop in Boulder right now, so I obviously won't be able to attend class this afternoon. Apologies! Best, Austin Herrema You are encouraged to attend conferences and workshops. I can provide some support for such activities (but not all).

7 7 6. Attending conferences/writing papers/lab Writing papers is fantastic! …and writing joint papers is especially exciting (and useful).

8 8 6. Attending conferences/writing papers/lab Wind Energy Lab – Room 1101 Coover, Nick David, Lab-scale turbine is in, consider what you might do with it. Nick can help.

9 9 7. Level 2 course considerations Proposed “Recommended Criteria for Evaluating Thrust Area Course Requests” The course topics must be relevant to the research context of the thrust area. Will the course enable students to conduct research in the thrust area? If a student is not conducting research in this thrust area would they learn something related to wind energy? Independent study requests (590) should be submitted accompanied with some documentation (see WESEP 590 form – next page). Recommended Thrust Area Course Policies Course requests that are not approved for addition to a thrust area can be evaluated on an exception basis. Students must provide a rationale for why the course is necessary for their research and how it is related to a thrust area. To ensure that students do not take all their course work in one discipline, at least 2 of the thrust area courses must be taken outside the disciplines of the students’ home department. Encouraged for all students. Required for students starting Fall 2014 or later.

14 Wind Energy Research Taxonomies ISU Wind Energy Initiative (2012): 14 Meteorology, Siting, Characterization, and Prediction: Wind resource characterization and forecasting through model simulation is a high research priority for guiding both on-shore and off-shore wind energy build-out. Additionally, wind reduction by upwind turbines reduces power available to their downwind nearest neighbors, which ultimately leads to total farm production below installed capacity. Aerodynamics, Loads, Control and Design, Noise: Unsteady loads; Aerodynamic interference of blades, tower; Computational simulation multiple turbines and optimization; Micro and macro siting of turbines; Aerodynamic tailoring of blades and design; Noise prediction and simulation Nacelle, Blade, Gearbox, and Drivetrain: Towers: Foundation and Construction: Design taller towers and foundations; Improve foundation efficiency; Floating foundations for off-shore applications; Minimize transportation, site development and construction costs; Accelerate construction; Structural monitoring of tower-foundation systems; Build tall tower test beds Materials, Manufacturing, Supply Chain, Transportation: 1) Reduce the cost to manufacture turbine components; (2) Enable designs that have better performance characteristics; (3) Reduce variability, which impacts both designs and downstream costs in the plant and in the field; (4) Reduce cycle time to making turbines, putting more turbines in place sooner and cheaper. Grid Integration, Transmission, Variability, and Electrical Systems: Automatic generation control, real-time and day-ahead markets, grid variability, interregional transmission design. Reliability: Nondestructive Evaluation, Operation, and Maintenance: Policy: Sustainability, Legal and Social Acceptance:

21 Wind Energy Research Taxonomies IEA Wind2, “End-of-term report 2009-2013 and Strategic Plan 2014-2019,” International Energy Agency, July 2013. 21 1.Wind characteristics: Address wind characterization to improve accuracy of resource assessment for optimal siting & operation of wind power plants & turbines, reduce wake array losses, produce more accurate forecasting of performance & output. These active tasks are the beginning of what is expected to be long-term, sustained collaborative effort to characterize wind at atmospheric, wind plant, & turbine levels. 2.Wind power technology: Explore system design and advanced controls at the turbine and wind power plant levels, for both land-based and offshore wind, to reduce maintenance costs and increase production. Activities will assess advanced components including rotors, drivetrains, power electronics, support structures, manufacturing and installation, and reliability and testing. Wind Power technology research activities reduce wind cost of energy through innovations in components and structures that result in reduced cost or improved energy capture. Technology research can also impact social acceptance. For example, innovations that reduce turbine noise, or floating offshore wind turbines that are out of the view from shorelines are technology developments that improve wind deployment acceptance. 3.Wind integration: Conduct research on power system operation/grid integration of high amounts of wind generation. R&D activities will publish information on power system operation with wind to enhance transmission planning/development, improve power system operation; & improve internal grid within wind plants. 4.Social, educational, and environmental issues: Conduct research on issues that affect wind siting, acceptance, & maximization of social benefit. R&D will explore social acceptance, cost of wind energy, environmental impacts, & tools to effectively communicate & manage impacts of wind development & help direct research investments. Research related to social, educational, & environmental issues directly informs regulatory & permitting process, enabling authorities to make well informed decisions regarding wind deployment. As knowledge is shared with regard to these issues, the regulatory/permitting process has potential to become more streamlined & timely, reducing pre-construction licensing costs to wind developers. Also understanding social issues & the elements of wind energy costs will help guide investments in all research categories. 5. Communication: The communications priority area ensures that the information developed through important research tasks is delivered to the appropriate wind energy stakeholders and increases the sharing of best practices. Communications activities will coordinate and share information internally within IEA Wind for smooth operation of the agreement. At the same time, the results of R&D work performed in the other priority areas will be disseminated in different ways appropriate to the target audience.
